Address displayed wrongly in Virtual Fabric

We are just starting to use FICON on our existing midrange SANs so have been testing setting up a virtual fabric to allow for the FICON settings. So far we have ahd no joy seeing the Mainframe connection but I think this may be a hardware issue. However I am suspicious of the way the "Address" appears in the switchshow display - the rest of the display is fine but the Address field reflects the order that these ports were added to the virtual switch. I would have expected these to appear as 6901/690A/690B/690C rather than as they do in the example pasted below. Examples that I have seen in manuals seem to indicate that this is wrong.
